Understanding the Evaporator Core: Function, Failure, and Replacement When it comes to vehicle air conditioning systems, one component that plays a crucial role is the evaporator core. Often overlooked, this component is essential for maintaining a comfortable cabin temperature during those hot summer months. What is an Evaporator Core? The evaporator core is a heat exchanger located within the vehicle's air conditioning system. Its primary function is to absorb heat from the cabin air, allowing the air conditioning system to cool the air circulated inside the vehicle. The core is typically made of aluminum or copper and consists of a series of tubes and fins that facilitate the heat exchange process. How Does the Evaporator Core Function? The process begins when the vehicle’s air conditioning system is activated. The compressor circulates refrigerant, a fluid that changes states between gas and liquid, through the system. Here’s a simplified overview of the evaporator ... read more

Understanding Diesel Aftertreatment Systems: Key Components and Common Issues Diesel engines are renowned for their power and efficiency, making them a popular choice across various industries, from transportation to construction. However, with the increasing focus on environmental regulations, diesel aftertreatment systems have become essential in minimizing the environmental impact of diesel emissions. This blog article delves into the components and functions of diesel aftertreatment systems while addressing common issues such as DEF fluid warnings, diesel fuel injector faults, soot sensors, NOx reduction, and more. What Are Diesel Aftertreatment Systems? Diesel aftertreatment systems are designed to reduce harmful emissions produced by diesel engines. These systems work in conjunction with the engine to eliminate pollutants such as nitrogen oxides (NOx), particulate matter (PM), and unburned hydrocarbons. Key components of diesel aftertreatment systems include: Diesel ... read more

Hybrid Battery Testing: Assessing Your Battery’s Health Before jumping to a hybrid battery replacement, it’s important to first assess the health of the battery through thorough testing. Hybrid batteries, like all batteries, lose their capacity to hold a charge over time. When this happens, your vehicle’s fuel economy and performance can take a hit. The goal of hybrid battery testing is to evaluate the overall condition of the battery, identify any weak cells or faulty components, and determine whether a replacement or repair is necessary. At Green’s Garage, we use state-of-the-art diagnostic tools to test the health of your hybrid battery. Our technicians conduct a comprehensive series of tests to determine factors such as: Voltage and Charge Capacity: We measure the voltage of each battery cell to ensure it is holding a proper charge. A drop in voltage across multiple cells can indicate the need for a battery replacement. Battery Balance: We assess the bal ... read more

Understanding Diesel Particulate Filter Systems Modern diesel engines are engineered to meet stringent environmental standards while delivering robust performance. One crucial component enabling this balance is the Diesel Particulate Filter (DPF) system. The DPF plays a vital role in reducing harmful emissions, ensuring that diesel-powered vehicles remain eco-friendly. However, issues with the DPF can lead to a dashboard warning light, altered driving performance, and costly repairs if not addressed promptly. This article explores the DPF system, why the warning light turns on, how it impacts driving, and what repair options are available.  What is a Diesel Particulate Filter? A Diesel Particulate Filter is an exhaust after-treatment device designed to capture and store soot particles emitted by diesel engines. These particles, often referred to as particulate matter (PM), are a significant contributor to air pollution and health hazards. The DPF’s purpose is to trap this s ... read more

Car Overheating Car overheating is one of the most common and potentially damaging issues drivers face. An overheating engine can not only disrupt your day but also lead to costly repairs if left unaddressed. Understanding the causes, signs, and solutions to overheating is crucial for maintaining your vehicle's health and ensuring your safety on the road. What Causes a Car to Overheat? An engine can overheat when its cooling system fails to manage the heat generated during combustion. There are two types of coolant leaks, an internal coolant which is when coolant seeps into the engine block and through the catalytic converter which will then emit white smoke. An external coolant leak is typically a component failure within the cooling system and coolant is often seen under the vehicle and/or a pinkish buildup can be seen at connecting points in the cooling system. Vehicle Overheating Repair Being able to recognize the warning signs of overheating can help yo ... read more
